To all whom it may concern:

Be it known that we, GEORGE T. PARRY and W. S. WARNER, both of the city ofPhiladelphia and State of Pennsylvania, have invented a new and useful mode of preventing leakage from barrels and other vessels of wood; and we do hereby declare that the following is full, clear, and exact description thereof.

Our invention consists in introducing paraftine into the pores of the wood. This may be We prefer to use the well-known. process, which consists in placing the barrels or other vessels, or the stoves or parts 0t wood composing the same, in any vessel made air-tight, or as nearly so as practicable, then exhausting the'vessel by means of an air-pump, and then allowing melted parafiine to flow into the vacuum. By this means the pores of the wood are saturated with the parafiine, and the Wood madeimpervions to coal-oil or the most powerful acids or other fluids.

Another mode of applying the paraftine to the wood consists in thoroughly drying the Wood in ovens or otherwise and then immersing it ina solution prepared by dissolving the par-aliiue in naphtha or other solvent.

Having thus described our invention, what we claim, and desire to secure by Letters Patcut. is-- The employment of peraffine to prevent leakage from barrels and other vessels of wood.
